Stormdry Repointing Additives

Description

Enhanced Waterproofing for Mortar Repairs

Stormdry Repointing Additives are concentrated waterproofing agents designed to improve the performance of mortar in masonry repointing projects. Simply dilute with water to create a gauging solution for sand/cement or lime-based mixes. Ideal for sealing cracks and preventing rain penetration through deteriorated mortar joints.

Two Options Available:

• Additive No. 1: Silane/siloxane blend for breathable water resistance – allows vapour to pass while blocking rain.
• Additive No. 2: Polymer-modified formula for maximum waterproofing and improved bonding – non-breathable.

Perfect for localized crack repairs or full wall repointing, especially when used alongside Stormdry Masonry Protection Cream.
